In celebration of Dunham's 27th birthday (on May 13), we are taking a look at some of her funniest fashion moments on "Girls." Between her mesh tank tops, snuggies and attempts to dress like a grown-up, we are always left LOLing at her, um, interesting sartorial choices.

When in doubt, wear mesh.

Floral capris should come with a warning.

Leave the costumes for Halloween.

When you break up with a sociopath, you end up wearing a snuggie (natch).

When you're trying to have a serious conversation, go for a high-waisted skirt.

Cupcakes and floral is our favorite combination too!
